sunrise, he will be pretty sure now and then to see the tail 

 end of the night 's migration . In indication of this a few entries 

 in last year's Journal may be quoted : — " September 14th, 1920. 

 At 5 a.m. it was too dark to see any migrants, nor could any 

 be heard passing over. September i6th, 7 a.m. Wind S. i. 

 Light enough to see several finches, probably Chaffinches, 

 coming in from the direction of the sea. September 25th. 

 A thick mist, no birds visible, but this does not necessarily 

 mean that migration is suspended, for under such conditions 

 they would presumably rise to a much higher altitude. 

 September 29th. The wind has changed to the south-east, 

 which according to Gatke {Heligoland, p. 76) is what 

 brings migrants nearest to the earth's surface. October 3rd, 

 7 a.m., S. 2, light pretty good. A certain number of Starhngs 

 coming from the sea, some Chaffinches, three Blackbirds and 

 a Mistle-Thrush or two, four Blue Tits flitting from tree to 

 tree." 



Migration in Lincolnshire compared ivith that in Norfolk. — 

 In Lincolnshire things seem to have gone rather differently, 

 for there Mr. Caton-Haigh informs me, the first " rush " 

 of birds was considerable. It began on September 30th and 

 coincided with a movement of Lapwings going west at 

 6 a.m. in Norfolk. As far as, Mr. Haigh's observation 

 went, it consisted almost entirely of Robins and Thrushes, 

 with Redstarts, Goldcrests, Bramblings, Chaffinches and 

 Tree-Pipits in very small numbers. The wind on that day 

 was east, force 4 at Spurn Head, and south 2 at Cromer, 

 but changed a little in the afternoon. This flight was 

 nearly over by October 6th, but a fresh immigration took 

 place on the coast of Lincolnshire on the 9th (wind N.E. 

 force 2 at Spurn), consisting of Goldcrests, Robins and 

 Redwings, with a few Ring-Ouzels and Rock-Pipits. This 

 fits in with Mr. Ben Dj^e's Yarmouth notes, as well as with 

 those of another good observer, who writing from near the 

 coast, says {in litt.) : " October 9. Hooded Crows migrating 

 west in good numbers, Ring-Ouzels, Redwings, Goldcrests, 

 Long-tailed Tits and Marsh-Tits are very much in evidence 



there are great numbers of birds to-day." From 



their geographical position, Lincolnshire and Norfolk have 

 much in common. 



The removal of the Leman and Ower Lightship calls for 

 some remark, as this was an admirable observatory, espe- 

 cially betore the lights were made to revolve (see Zoologist, 

 1912, p. 123), and one from which I have had some good 

 wings of birds (forty species or more). The Newarp L.V.
